General Information

A small member of the minnow family with an elongated body that is flattened ventrally. There are eight rays in the dorsal fin and seven in the anal fin. The lateral line has approximately 65 scales. Coloration tends to be olivaceous background, with a lot of blotches in darker pigments. There are whitish spots at the origin and insertion of the dorsal fin and dorsal and ventral portions of the caudal fin base. A black, basicaudal spot is usually present. Breeding males have bright red-orange coloration at the bases of the paired fins and on the adjacent body, on the base of the caudal lobe, about the mouth, near the upper portion of the gill opening, and often on the abdomen. Females in the breeding season become yellowish on the fins and lower body.

Habitat Requirements

Turbulent, rocky riffles of mainstream rivers and tributaries at or less than 2,200 meters in elevation. Habitat that is occupied is relatively shallow, has a moderate to swift current, with gravel to cobble dominated substrates. The depth, velocity, and substrate of occupied habitats can, and is expected to, vary seasonally and geographically.

Food Habits

Opportunistic, benthic insectivores, largely deriving their food supplies from among riffle-dwelling, larval flying insects (mayflies, black flies, and members of the Chironomidae family), larva of other aquatic insect groups (stoneflies, caddisflies), and occasionally pupae.

Movement / Home Range

The loach minnow was historically endemic to the Gila River Basin of Arizona, New Mexico, and Sonora, Mexico. Currently persists in Arizona in the White River of Gila County, the North and East Forks of the White River in Navajo County, Aravaipa Creek in Graham and Pinal Counties, San Francisco and Blue Rivers and Campbell Blue Creek in Greenlee County. In New Mexico, the species could be found in the upper Gila River, including the East, Middle and West forks of Grant and Catron counties, the San Francisco and Tularosa Rivers in Catron County, and the lowermost Whitewater Creek and Dry Blue Creek in Catron County

Reproductive Strategy

Loach minnow will first spawn at age one in late winter-early spring (Aravaipa Creek), and from late March into early June (New Mexico). Spawning is in the same riffles occupied by adults during the nonrepoductive season, where sex ratios appear approximately equal. Eggs are deposited on the underside of flattened rocks; cavities are usually open on the downstream side while the upstream portion of the rock is embedded in the substrate. The eggs have an adhesive quality to them.

Other

Threats to the minnow are predominantly water use based, and the alterations to stream habitat. These include impoundments, dewatering, non-native species, and livestock grazing.
